LT1's were underrated by GM??? The Camaro is rated at 275-285 hp. The Corvette was rated at 300 hp. I was told by a GM tech. that they all made about 311 hp and was underrated for insurance purposes. They just gave the Corvette a higher rating so it could be superior to the Camaro. Any truth to this guys???

Pretty sure its the difference in exhaust components and tuning mixed with the different air intake set ups. the WS6 and SS fbodys were rated 305hp i beleive too.
Really the main thing was the difference in the years. but all that was changed was catalytic converters and O2 sensors and tuning along with it.
Ls1's are deffinetly underrated, LT1's id say no.

I dont know how HP would affect insurance? I've never been asked how much HP my car has for insurance purposes, and it doesn't say anywhere on any insurance info either just "V8"...I doubt if I walked in and told them my Firebird had 600hp (it obviously doesnt, but just for argument's sake) they'd raise my insurance.
Also, remember not all the motors made the same exact HP...some made more, some made less. HP ratings are often times at the short end of the spectrum to ensure that you have "at least or around X HP" in almost every application. That's why some of the new 5.0 Mustangs run 12.80's and some run 13.30's

If you think about it stock LT1's are dynoing around 250-260rwhp. I would have to say that 311 flywheel hp sounds about right.

New cars are remarkably close in hp to one another with the improvements in machine work and assembly.

Yep because everyone is as equally good of a driver as the next and they run in the exact same conditions... And the fastest stock 5.0 down to the factory tires has gone 12.4 for the record.

Before this turns into a new 5.0 is the best car ever argument shitfest, lets remember that we're talking about LT1's here too, not new cars.

All GM cars are underrated. All of their crate motors are as well. Look at the new Camaro V-6. In 2010 they rated it at 304hp. Then the Mustang came out and trumped it with 305hp. So GM took the time to actually certify it according to the sae standards and lo and behold, it's rated at 312hp now, even though it's the exact same thing. It's just a little cushion built in to be on the safe side. Look at what happened to Ford with their '96 (I think thats the year i'm thinking of) Cobra's when they rated them at 300hp, and they weren't putting out near that kind of power. They had a nice class action lawsuit on their hands.

The way insurance companies look at it is: You have a more powerful engine, you're probably going to drive it faster and more dangerously. That's why it costs more.

Hell I got a guy emailing me about buying my car calling me a liar because it can't hit 12s! I showed him video of the car doing it and he still called me a liar!
Then he went on to tell me he owns 2 lt1s... sure ya do... sure you do.

I highly doubt that driver skill is going to be the only factor in a 1 second difference in 1/4 mile times between people who do it for a living...what im trying to say is that cars varry...you wouldn't expect every new 5.0 mustang to run 12.4's, would you?

Oh and he went 12.374 @ 114.45 now.
